Miike Coal Mine is registered as a world cultural heritage site. Miyanohara Pit is one of the mine’s architectural components that is part of the urban landscape, serving as a tourism resource. To formulate an effective preservation policy for the pit, Nagoya City University needed to survey and model the site. To ensure accurate results, they sought a comprehensive reality modeling application.

They selected ContextCapture to process 204 drone-captured photos and generated a 3D reality mesh of the area, eliminating the need to model the individual existing buildings, significantly reducing resource hours and costs. Using Bentley’s application enabled Nagoya City University to accurately digitalize the captured data for further investigation and analysis in terms of safety, maintenance, and preservation. The 3D digital model can be updated periodically to continually represent the real-world scenario and be used for restoration in the event of a building collapse or disaster, providing a sustainable solution for preserving the site.
